A feeding mechanism of bamboo chip fine planing machine

Abstract

The present invention provides a feeding mechanism for a bamboo chip fine planer, comprising a frame, a baffle, a material bin, a pushing assembly and a conveying assembly. Two groups of material bins are provided, which are respectively arranged at the two ends of the frame surface. The material bin comprises a left material plate, a right material plate and a lower material plate. Under the action of the pushing assembly, the bamboo chips at the bottom of the lower material channel enter the conveying channel, and the bamboo chips in the conveying channel are arranged side by side. The pushing assembly pushes the bamboo chips in the conveying channel outward, and cooperates with the conveying assembly to send the outermost bamboo chips into the fine planer. When the outermost bamboo chip has not completely entered the fine planer, the next bamboo chip has been pushed out and contacts the side of the previous bamboo chip. After the end of the previous bamboo chip exceeds the front end of the next bamboo chip, due to the thrust of the pushing assembly, the side end of the second bamboo chip contacts the conveying assembly again to drive the bamboo strips forward. This feeding method can realize the bamboo chips entering the fine planer in a head-to-tail manner, thereby greatly improving the production efficiency.

Description

Technical Field

[0001] The invention relates to the field of mechanical equipment, in particular to a feeding mechanism of a bamboo chip fine planer. Background Art

[0002] Most of the existing fine planer feeding mechanisms are too inefficient, and can only feed about 20 bamboo strips per minute. In addition, there are empty materials or multiple materials entering the feeding trough. To solve the above problems, the feeding mechanisms on the market currently adopt the method of accelerating the feeding speed so that the frequency of a single material can be roughly equal to the fine planing frequency of the fine planer, thereby meeting production needs. This method usually requires adding signals to monitor empty materials and multiple materials, which undoubtedly increases the equipment cost. Summary of the invention

[0051] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0052] Please refer to Figures 1 to 6 The present invention provides a feeding mechanism of a bamboo chip planer 8, comprising a frame 1, a baffle 5, a silo 2, a pushing assembly 3 and a conveying assembly 4;

[0053] There are two groups of silos 2, which are respectively arranged near the two ends of the surface of the frame 1. The silos 2 include a left material plate 21, a right material plate 22 and a lower material plate 23;

[0054] The left material plate 21 and the right material plate 22 are arranged opposite to each other at a distance, and a vertical material discharge channel is formed between the left material plate 21 and the right material plate 22;

[0055] The feed plate 23 is arranged below the left feed plate 21 and the right feed plate 22, and a feeding channel is formed between the feed plate 23 and the left feed plate 21. The feeding channel only allows a single bamboo piece to pass along the length direction of the feeding channel, and the feeding channel can accommodate at least two bamboo pieces side by side. One end of the feeding channel is connected to the feed plate 23 to form an L-shaped channel with the feed plate 23.

[0056] The conveying assembly 4 is arranged on the frame 1 at the opening of the material conveying channel of the material bin 2 near one end of the fine planer 8, and is used to convey the first bamboo piece at the opening of the material conveying channel toward the fine planer 8;

[0057] The baffle 5 is fixed on the frame 1 and is used to block the second bamboo piece in the feeding channel from being transported toward the fine planer 8;

[0058] The pushing assembly 3 is installed on the frame 1 and is used to push the bamboo pieces in the unloading channel toward the feeding channel;

[0059] When in use, the bamboo chips are stacked and placed in the feeding channel. Under the action of the pushing component 3, the bamboo chips at the bottom of the feeding channel enter the feeding channel, and the bamboo chips in the feeding channel are arranged side by side. The pushing component 3 pushes the bamboo chips in the feeding channel outward, and cooperates with the conveying component 4 to send the outermost bamboo chips into the fine planer 8. When the outermost bamboo chip has not completely entered the fine planer 8, the next bamboo chip has been pushed out and contacts the side of the previous bamboo chip. After the end of the current bamboo chip exceeds the front end of the next bamboo chip, due to the thrust of the pushing component 3, the side end of the second bamboo chip contacts the conveying component 4 again to drive the bamboo strips forward. This feeding method can realize the bamboo chips entering the fine planer 8 in a head-to-tail manner, which greatly improves the production efficiency.

[0060] In this embodiment, the pusher assembly 3 includes a guide rail 31, a first cylinder 34, a second cylinder 35, a first slider 32, a second slider 33 and a pusher plate 36;

[0061] The guide rail 31 is fixed on the frame 1;

[0062] The first slider 32 and the second slider 33 are both slidably mounted on the guide rail 31;

[0063] The first cylinder 34 is installed on the guide rail 31, and the piston rod of the first cylinder 34 is connected to the first slider 32;

[0064] The second cylinder 35 is a low-pressure cylinder, which is mounted on the first slider 32, and a piston rod of the second cylinder 35 is connected to the second slider 33;

[0065] The push plate 36 is installed on the surface of the second slider 33;

[0066] The air pressure of the second cylinder 35 is lower than that of the first cylinder 34. Since the air pressure of the second cylinder 35 is low, when it touches the bamboo piece and the bamboo piece touches the roller 41, the second cylinder 35 plays a buffering role to prevent the friction between the bamboo piece and the roller 41 from being unable to drive the bamboo piece into the fine planer 8. In addition, the second cylinder 35 can also adapt to bamboo strips of different widths. When the bamboo strip is wider, the bamboo strip touches the roller 41 before the narrow bamboo strip. At this time, after the touch, since the air pressure of the first cylinder 34 is high, the second cylinder 35 will retreat and adjust to the state of pressing the bamboo strip but will not make the bamboo strip locked and unable to move; when the bamboo strip is narrow, after the first cylinder 34 reaches the movement stroke, the second cylinder 35 will continue to move forward and gradually push the bamboo strip to gradually touch the roller 41; when a piece of bamboo strip in contact with the roller 41 moves forward and enters the fine planer 8, the cylinder can retreat for the next push, so as to meet the orderly movement of bamboo strips of different widths.

[0067] In this embodiment, the height of the plane where the upper surface of the push plate 36 is located is 2-4mm higher than the height of the plane where the upper surface of the lower plate 23 is located, which enables the push plate 36 to effectively push the bamboo piece at the bottom of the feeding channel. In addition, since the push plate 36 is 2-4mm higher, after the push plate 36 pushes out the bottom bamboo piece, the remaining bamboo pieces in the silo 2 are lifted up by 2-4mm as a whole under the support of the push plate 36, further preventing the second to last bamboo piece from being brought out of the silo 2. After the push plate 36 is retracted, the bamboo pieces in the silo 2 fall down as a whole to return to their original positions.

[0068] In this embodiment, the conveying assembly 4 includes a motor 45, a reducer 44, a bearing seat 43, a rotating shaft 42 and a roller 41;

[0069] The bearing seat 43 is mounted on the frame 1;

[0070] The rotating shaft 42 is installed in the bearing seat 43, and one end of the top of the rotating shaft 42 is connected to the roller 41, and one end of the bottom of the rotating shaft 42 is connected to the reducer 44 and the motor 45 in sequence; when in use, the motor 45 drives the rotating shaft 42 to rotate through the reducer 44, and the rotating shaft 42 drives the roller 41 to rotate, and the bamboo pieces in contact with the roller 41 cooperate with the thrust of the pushing assembly 3, thereby driving the bamboo pieces to move forward.

[0071] In this embodiment, it also includes an optical axis 6, which is arranged at the opening of the material feeding channel of the silo 2 on the frame 1 away from the end of the fine planer 8. The rear end of the bamboo strip is limited by the optical axis 6. When the front and rear ends of the bamboo strip are simultaneously thrust by the cylinder and contact the roller 41, the bamboo strip cannot move forward and enter the fine planer 8. After many tests, it was found that the bamboo strip can smoothly enter the fine planer 8 without the roller 41 at the rear end.

[0072] In this embodiment, the left material plate 21 is connected to the height adjustment component 9, and the height adjustment component 9 includes an adjustment rail 91 and an adjustment slider 92. The adjustment rail 91 is vertically arranged, and the adjustment slider 92 is slidably installed on the adjustment rail 91 and fixed by bolt fasteners. The left material plate 21 is fixedly installed on the adjustment slider 92. By adjusting the height of the left material plate 21, bamboo pieces of different thicknesses can enter the feeding channel.

[0073] In this embodiment, an L-shaped supporting plate 7 is also included. The L-shaped supporting plate 7 is arranged on the frame 1 and located between the two groups of silos 2 to prevent the tail of the bamboo strips from swinging or sagging when entering the fine planing machine 8.

[0074] The working principle of the present invention is as follows:

[0075] The bamboo pieces are stacked and placed in the feeding channel. Under the action of the pushing component 3, the bamboo pieces at the bottom of the feeding channel enter the feeding channel, and the bamboo pieces in the feeding channel are arranged side by side. The pushing component 3 pushes the bamboo pieces in the feeding channel outward, and cooperates with the conveying component 4 to send the outermost bamboo pieces into the fine planer 8. When the outermost bamboo piece has not completely entered the fine planer 8, the next bamboo piece has been pushed out and contacts the side of the previous bamboo piece. After the end of the current bamboo piece exceeds the front end of the next bamboo piece, due to the thrust of the pushing component 3, the side end of the second bamboo piece contacts the conveying component 4 again to drive the bamboo strips forward. This feeding method can realize the bamboo pieces entering the fine planer 8 in a head-to-tail manner, which greatly improves the production efficiency.

Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
